ATTACHMENT FOR CANOES.

Application filed November '12, 1924. Serial No. 749,542.

To all 107mm it mtm concern.

Be it known that I, 'CrrARLEs L. EDWARDS, a citizen of the United States, residing at l-Iackensack, in the county of Bergen and 5 State of New Jersey, have invented certain new and useful Improvements in Attachments for Canoes, of which the following is a specification.

My invention relates to boat attachments 19 and more particularly to a safety attachment for canoes and the like.

It is an object of the invention to provide a pair of sponsons attachable to the sides of a canoe which will prevent the canoe from tilting or upsetting when in use.

A further object of the invention is to provide means of the above character which may be detachably connected with the canoe, so the same may be easily removed when desired.

A further object of the invention is to provide sponsons designedso as to not interfere with .the propulsionof the canoe and which will deflect the refuse and snags strik- 25 ing the sponsons while the canoe is in :mo-

tion.

Another-objectof the invention is to provide an attachment of the above mentioned character which is simple and durable in construction, reliable and eflicient in operation and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying; drawings formin a part of this specification and in which llke numerals are employed to designate like parts throughout 'the same, E

Fig. 1, is a plan view of a canoe with the invention attached thereto.

Fig. 2, is a side elevation of the same, Fig. 3, is a cross sectional view of the same,

Fig. 4, is a plan view of a canoe with a modified form of the invention attached thereto,

Fig. 5, is a side elevation of the modified form,

Fig. 6, is a cross sectional view of the same, and,

Fig. 7 is a detail sectional view of the attachment.

In the drawings, wherein for the purpose of illustration I have shown a preferred embodiment of my invention, the numeral 5 denotes a conventional type of canoe having the usual gunwales6.

Referring more particularly to'my invention a sponson 7 is connected to each side of the canoe, approximately lnidwaythe length thereof. The sponsonis a hollow compartment or air chamber constructed of light material, of substantially semi-circular sha e in cross section, with itsunderside slig itly flattened, as at 7 "The ends of the sponson are tapered inwardly and upwardly towardsthe side of the canoe, as at 8, which serve to deflect the refuse and snags which contact with the sponsons while the canoe is in motion. The sponsons are sus- T9 pended from the gunwales by angular projecting arms 9, having one end attached to the gunwale, as at S), and the opposite end to the top of-the sponson, as at 10,:at opposite ends thereof. The centerof the sponson is braced by the "T-shaped arm 11 which is connected with the sponson and gunwale. The sponsons extend down the side of the canoe, into close proximity of the water line, so a slight tilt of the canoe will move the sponsons into contact with the water.

When it is desired to use the canoe as a sail boat, the leeboards 12 may be attached to the inner side 12 of the sponsons in any suitable manner, and thereby, dispense with the use of the usual sailing rig.

In Figs. 4 to 7 inclusive, a modified form of the invention is shown in which the sponsons are connected with the canoe by an angle bar 17 extending longitudinally of and fitted over the gunwale, so the side 18 of the bar depends on the outside of the canoe, to which the sponsons 7 are attached by screws 19. A U-shaped clamp 13 is formed integral with each end of the bar 17, each clamp having an arm 14 extended over the gunwale lnside the canoe and se cured in place by a set screw 14:. To space the sponson from the side of the canoe a filler block or blocks 15 are inserted between the side 18 of the bar 17 and the body of the canoe having a shoulder 16 to receive the gunwale and establish a tight fit.

In practice, it is well known that a canoe in the hands of an experienced person is reasonably safe, but extremely dangerous and unsafe in the hands of inexperienced persons. It is the purpose of my invention to provide means easily attachable to the canoe whereby the same will be rendered perfectly safe. This is accomplished by providing sponsons having means for readily attaching them to the sides of the canoe. The sponsons are spaced from the sides of the canoe and depend into close proximity to the water line, whereby tilting or upset ting of the canoe will be counteracted by the buoyancy of the sponsons on striking the Water. It will also be observed that when it is desired to use the canoe as a sail boat, the sponsons can be attached to the canoe and the lecboards connected to the sponsons, thereby dispensing with the usual sailing rigs. Most attachments for canoes are objectional because they impede the movement of the boat, and to prevent interference with the movement of the canoe, by reason of snags or refuse in the water contacting with the sponsons, the ends of the sponsons are tapered so the refuse and snags will be deflected away from the canoe.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that certain changes in the shape size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention I claim:

1. An attachment for water-craft comprising a pair of sponsons, an angle bar extending longitudinally of said sponsons and connected therewith, and U-shap-ed clamps formed integral with said bar for attaching the same to the sides of the craft.

2. An attachment for water-craft comprising a pair of sponsons, an angle bar ex tending longitudinally of said sponsons and 3. An attachment for water craft comprising a pair of sponsons, means for connecting said sponsons to the water craft and leeboards detachably connected with and depending lrom said sponsons.

4. In combination with water craft, a

support for an attachment of the character described comprising a longitudinal angle bar, clamps at each end of said bar for attaching the same to a craft, and filler blocks inserted between said bar and the side of the craft.

5. In combination with water craft a support for an attachment of the character described comprising a longitudinal angle bar and clamps at each end of. said bar for attaching the same to a craft.

6. An attachment for water craft comprising a pair of sponsons, an angle bar extending longitudinally of said sponsons and connected therewith, clamps at each end of said bar for attaching the same to the craft, and leeboards detachably connected to the inner side of said sponsons and depending below the bottom thereof.

In testimony whereof I aflix my signature.
